1、编译sample程序
cd /home/hisilicon/3519A/Hi3519AV100_SDK_V2.0.2.0/smp/a53_linux/mpp/sample
source /etc/profile
make
2、编译hisilicon驱动
SDK中自带的驱动加载时有报错，猜测可能是toolchain更新的原因，偿试重新编译驱动
/ko # ./load3519av100 -i
mmz_start: 0x32000000, mmz_size: 1760M
sys_config: loading out-of-tree module taints kernel.

重新编译驱动后再次加载时正常
/ko # ./load3519av100 -i

# 编译文件中配置的内核文件目录名为linux-4.9.y-smp，实际编译内核时目录为linux-4.9.y，会造成编译驱动时找不到内核文件报错，解决办法创建软链接

3、运行样例程序
加载驱动后直接运行样例程序有报错，提示缺少库文件
./sample_tde 1
./sample_tde: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
查看所以依赖库文件，对比rootfs/lib目录，发现少了libstdc++.so.6，如果只拷备此库文件，再次运行会提示缺少另外的库文件，应该是此库文件还依赖其它库文件，所以需将对应的目录的所有库文件复制到开发板rootfs
arm-himix200-linux-objdump -x sample_tde | grep NEEDED
NEEDED libpthread.so.0
NEEDED libm.so.6
NEEDED libdl.so.2
NEEDED libstdc++.so.6
NEEDED libc.so.6
NEEDED ld-linux.so.3
使用find / -name libstdc++.so.6 在交叉工具链中查找对应的库文件，将相应目录的库文件全部拷入rootfs/lib/a53_softfp_neon-vfpv4/目录中
# 开发环境
cp -R /opt/hisi-linux/x86-arm/arm-himix200-linux/arm-linux-gnueabi/lib/a53_softfp_neon-vfpv4/* /home/hisilicon/3519A/nfs/rootfs/lib/a53_softfp_neon-vfpv4/
cp
# 3519开发板，此处需注意sample_tde对应的res文件夹需一起复制到rootfs，否则运行时会提示res中的资源文件找不到
./sample_tde 1
# hdmi输出可正常显示多个图标转动
